#1
Which of the following is a symptom of a heart attack?
Chest pain or discomfort
ExplanationChest pain or discomfort is a common symptom indicating a possible heart attack.
#2
Which of the following is a risk factor for developing cardiac events?
High blood pressure
ExplanationHigh blood pressure is a common risk factor associated with increased likelihood of cardiac events.
#3
What is the recommended first step in responding to a suspected cardiac arrest?
Call emergency services (911)
ExplanationCalling emergency services (911) is crucial for timely intervention during cardiac arrest.
#4
Which heart rhythm is considered a shockable rhythm during cardiac arrest?
Ventricular fibrillation (VF)
ExplanationVentricular fibrillation (VF) is a shockable rhythm, requiring immediate defibrillation.
#5
What is the purpose of using an automated external defibrillator (AED) during a cardiac emergency?
To deliver an electric shock to the heart
ExplanationAEDs deliver electric shocks to restore normal heart rhythm during a cardiac emergency.
#6
What is the purpose of the 'chain of survival' concept in emergency medical response for cardiac events?
To outline the steps needed to address cardiac emergencies
ExplanationThe 'chain of survival' outlines the sequential steps to improve survival from cardiac emergencies.
#7
What is the recommended compression-to-ventilation ratio for CPR in adults?
30 compressions to 2 ventilations
ExplanationThe recommended ratio for CPR in adults is 30 compressions to 2 ventilations.
#8
What is the recommended depth for chest compressions in adult CPR?
At least 2 inches (5 centimeters)
ExplanationChest compressions during adult CPR should be at least 2 inches deep to effectively circulate blood.
#9
What is the acronym 'ABCDE' used for in emergency medical response?
To assess airway, breathing, circulation, disability, and exposure
ExplanationThe 'ABCDE' acronym guides the systematic assessment of critical aspects during emergency medical response.
#10
What is the recommended ratio of chest compressions to breaths in CPR for infants?
15:2
ExplanationFor infants, the recommended ratio of chest compressions to breaths in CPR is 15:2.
